BASH -ANTIRATTLER.

Application filed February 10, 1921. Serial No. 443,874.

' The frame facings are very narrow so that there is very little spacefor the placement of anti-rattling devices. -Moreov.er in view of thefact that these anti-rattling devices must engage directly with theglass. the 2 pressure applied cannot be greatas otherwise theglass isliable to be broken under the strain imposed; moreover care must betaken that the glass is not scratched by the sash engaging element ofthe anti-rattling device.

One of the objectsof this invention, therefore, is to provide ananti-rattler designed more particularly for closed automobiles and whichwill hold the sash effectively 0 without'dangerof breakageordisfiguration. Another object is to provide a device of the kinddescribed which is simple. cheap to make, easily applied. durable, notliable to get out of order. which is attractive in a pearance and willnot mar theframe to wliich it is attached, and which is eflicient inoperation.

Further objects will appear from the detail description taken inconnection with the accompanying drawing. in which:

Fig. 1 is a side elevation of my improved anti-rattler shown mounted-intheantirattling position on a window frame.

Fig. 2 1s a view similar to Fig. 1', showing the anti-rattler in therelease positionf Fig. 3 is a cross section on the line 3-3 of Fig. 1. 1J

SimiEa-r reference characters designate similar parts in the differentviews.

Referring-to the accompanying drawing. 1 designates. a supportmg memberor bear- 111g shank. preferably a wood screw. which is adapted to bescrewed into a window frame 2. adjacent to a vertically slidable sash orglass plate 3. mounted in the window frame 2.

Mounted'on the screw 1 is a washer or base 4 having one or more inwardlyextending projections 5 adapted toenter the frame 2. to hold the washerfrom turning on the screw. The outer side of the washer 4 has Fi .6ancl7.

otatably mounted on the screw 1 is an outer plate or facing 7 and aninner plate or facing 8. between which is mounted a resilient memberpreferably a soft rubber disk 9. the facings terminating withinthe'periphcry of the disc. so that the latter extends beyond thefacings. This disc and its facings are eccentricallv and rotatablymounted on the screw 1 and which is adapted to be compressed. betweenthe plates '7 and 8. when the screw 1 is screwed to a pre-determinedposition in the window frame. Means such as a pin 10 whichextends'through the plates 7 and 8 and disk9, is provided to hold thedisk fromturning relatively to the plates 7 and 8.. I

The disk 9 is adapted to be turned on the screw 1 from the releaseposition shown in in this embodiment a roughened surface 6. I

Fig. 2.- to the position shown in Fig. 1. in

which latter position the disk 9 will be adapted to engage and becompressed by the glass plate 3. so as to hold the latter from rattlingin the frame. i

The inner side of the plate 8 may be provided with a roughened surface11. which engages the surface 6 of the washer 4 so as to hold the plate8 and with it the disk 9 in the manner described, the sash. plate 3 vmay be held from rattling and also from accidental verticalmovement, byswinging the disk 9 to the anti-rattling position shown in Fig. 1,'inwhich positionthe disk 9 will be compressed against the plate 3, therebypreventing he sash from rattling. The resilient disk 9 will yieldsufliciently, however, when in the anti-rattling position, to permit thesash being manually raised or lowered Without having first to turn thedisk from the locking position and without marring or facings acts as acushion or spring, so that when the faced disc is rotated against theglass sash, the rubber is compressed to cause even'wedging engagementtherewith. This yield is permitted on account of the fact that the dischas a rubber bearing on the bearing shank, for'the rubber can actually.be displaced between the disc in a direction away from the sash andwith respect to the bearing shank and with respect to even the rivetsecuring the facings and the disc together., Accordingly, the elementcan even be rotated still further from the positionv shown in Figure 1until the rivet is in line with the bearing shank, which will causemaximum tensional engagement, as the effect is that of a toggle beingstraightened, so that a rotating pressure applied to the disc by eventhe finger and thumb will be suflicient to cause engagement of therubber disc with the glass sash. This can be readily accomplished whenthe bearing shank orscrew is loose as soon, however, as the element hasbeen properly positioned, the screw can be tightened and it then servesnot only to clamp the faced disc to the frame, but also toclamp the discbetween the facings. Ac-

cordingly the screw and the facings operate to brake the movement of thefaced disc to theextent of the clamping action, which can be varied inaccordance with the extent that the screw is tightened. Accordingly,while the disc can be readily rotated to secure a firm grip on the sashand to hold it firmly against rattling, it can also be braked or lockedin engaging position so as not to be shifted by the yibration of theautomobile and of the sash therein as is usually the case. This isespecially true since not only is the disc braked against suchmovement,-but in view of the fact that the axis about which the disc isrotatable is within the periphery of the disc, the latter can be placedso that the point of contact between the disc and the glass sash, Wherethe pressure is the greatest, passes through the center of the disc aswell as theaxis of the bearing.

While, however, the element firmly holds the sash against rattling andwhile this element in turn is firmly held against shifting,

nevertheless the structure is such that the sash can readily'be raisedor lowered; this can be accomplished not only on account of the factthat the pressure is ayielding one, but also on account of the.fact-that due to the nature of the construction a tangential movement ofthe sash with respect to the periphery of the disc is readily permitted,while radial movement is firmly but yieldingly opposed.

I do not limit my invention to the structure shown and described, asmany modifications, within'the scope of the appended claims, may be madewithout departing from the spirit of my invention.

What I claim is'- '1. In I a sash anti-rattler, a supporting memberadapted to be mounted in a window frame, a washer mounted on said memberand arranged to bear against said frame, two plates ro-tatably mount-edon the supporting member, one having frictional engagement with thewasher, and a resilient member eccentrically mounted on the supportingmemher and adapted to be clamped thereby between said plates, saidresilient member being adapted to engage and to be compressed by a sashslidably mounted in said window frame, substantially as set forth.

2. In a sash anti-rattler, a screw adapted to be mounted in a windowframe, two plates rotatable on the screw andmovable one toward the otherby the screw, and a resilient member eccentrically and rotatably mountedon the screw and adapted to be clamped between said plates, saidresilient member being adapted to be engaged and compressed by a sashslidable in said window frame, substantially as set forth. I

3. In a sash anti-rattler, a screw adapted to be mounted in a windowframe, a washer mounted on the screw and provided with means forengaging the window frame to hold the Washer from turning, two platesmovable toward and fro-m each other and rotatable on the screw, one ofthe plates having frictional engagement with the washer, a resilientdisk ecc'entrically and rotatably mounted on the screw between andadapted to be compressed by said plates and adapted to engage and to becompressed by a sash slidable in the window frame, and means for holding4 said resilient member from turning relatively tosaid plates,substantially as set forth.

4. In a sash anti-rattler, supporting means adapted to be fastened to awindow frame, two clamping plates rotatable thereon, one being movabletoward and from theother, the other being adapted to exert pressureagainst the window frame, a resilient member ecoentrieally and rotatablymounted between said plates on said supporting means, said supportingmeans being arranged to force the movable/clamping plate toward theother clamping plate so as to compress said resilient member betweensaid clamping plates. said resilient member serving to yieldingly presssaid other clamping plate toward said window frame. and means forholding the resilient member from relative turning between said clampingplates. substantially as set forth. 7

5.
